MANURE SFREADER.

Application filed June 9,

To of] lwlw/m, it :may @mic-cm.:

l-e it known that l, HENRY SYNCE, a citizen of the United States, and a resident` of Coldwater, in the county of Mercer and fitate oit' hio, rave invented certain new and useful Improvements in Manure Sprcaders, ot which the following:T is a full, clear, and exact description.

rthe invention relates to manure-spreaders.

(ne object of the invention is to provide an improved constrnction in which provision is inade tor preventing the inanure from be coming wrapped around and entangled with the tooth-supporting` bars of the cylinder.

Another object of the invention is to provide improved ineans tor preventingl the tootlfcarrying bars of the cylinder 'frein cuttingt into the sides of the box or traine.

Another object ot the invention is to provide an improved construction oiZ the cylind ,-r which is durable and ei'tlcient in operation.

still turther object oit the invention is to provide in'iproved ineans tor preventing` the rear axle troin binding in the bearings which are secure( to the sides of the convevor-box.

'The invention consists in the several novel tea-tures hereinafter set forth and n'iore particularlu defined by ciahns at the conclusion hereof.

ln the drawings: Fig. 1 is a vertical longitudinal section or the rear portion ot a inanure-spreader embodying the invention, 2 is a detail of one of the connections between one or the heads and one ot1 the tooth-supporting` bars. Fig. 3 is a section taken on line 3-3 of Fig. 1. Fig. 4 is a detail section ot' one of the axle-bearings and Fig. 5 is a perspective of the bearing;- sleeve. Fig. 6 is a detail ot one end ot the band adjacent one end of the lower cylinder.

The invention is exeinplilied in a spreader comprising` a box having sides 7 and a bottoni 7a, an endless chain and seat conveyor 8, a distributer-cylinder 9, an upper cylinder 10, anA axle 11, and carrying wheels 12. In the type of spreader illustrated, the cylinders and conveyor are usually driven by power derived troni the wheel axle and. through suitable gearing, as well understood in the art. Only the rear portion of the spreader has been illustrated, because the invention is embodied in that, and the front i919. Serial No.v 362,654.

portion inay be ot any suitabley or known constri'lction.

rlhe distributer cylinder 9 is mounted upon a shaft 13 which is carried by bearings 111 and extends through the-box-sides 7, and comprises a pair of heads 15 each 'ot' which has a hub secured to the shaft 13 and curved laterally extending lugs 17, each adapted to receive a 'tubular bar 18 in which the cylinderteeth 19 are lined. Bolts 2O extendingl through lugs 17 and bars 18 secure each bar rigidly on the heads. Each lug` is provided with an outwardly open seat 21 which is pro-vided with a recess 22 disposed inwardly oi the bar, so that, when the nut ot the bolt forces the bar 18 into the seat, itwill perinit slight distortion or" the tubular bar into said recess which will cause the bar to be incre lirinly clamped in the seat. As the result oi? employingl round or tubular toothsupporting bars and open seats in the heads, tendency for the manure to becoine entair glcd adjacent and around 4the heads is ininiini/Zed. The teethl) are driven through the tubular .bars 1SA and lixedly heldtherein. A hand 25 is provided at each end of the cylinder 9 and each of these bands is provided with a ineinber 26 abutting against the inner face ot a box-side 7 and secured in position by bolts 27 and comprises also an inturned flange 28 which is outside of and laps the ends oi' the bars 18 to prevent the inanure from becoming entangled and wrapped around said Vends. The member 26 of band 25 prevents the bars 1B from cutting` into the sides 7 which are usually formed ot wood, in event there should be any lateral play of the cylinder. Each band is cut away at its rear end and its lower end is curved as at 25 to centralize the bars 18.

rEhe upper cylinder is mounted on a shaft 30 and comprises heads 31, tubular hars 32 secured to said heads, and teeth 33 secured in said bars. lllhe bars 32 are secured to the heads 81 in inanner hereinbefore described in connection with the bars and heads of the distributer-cylinder 9. A deflecting ring,- or plate 34 is provided at each end of the cylinder 10 and has a Acurved 4flange 35 which extends to a point inwardly of the ends oil the bars 32 and serves to deliect the inanure frein the ends of said bars so that it will not becoine wrapped around or entangled with thein. Said rings are secured to the box-sides 7 by bolts 36.

well

Mechanism for driving the cylinders is exemplified by a sprocket 3T suitably driven by the axle 11, a chain 38 which extends around sprockets 89 and Li() on the shafts 13 and 30 respectively to drive the cylinders .3 and l0. v

In practice, it sometimes occurs that the parts of the frame-work or box are not truly aligned or become distorted. rThis subjects the rear axle and its bearings to binding stresses which causes excessive wear. To meet this difficulty, theV axle-bearings 48, which are secured to the box-sides 7 respectively, are provided with vsleeves 44. Each sleeve is slightly tapered as at 45 to permit sufficient movement in the bearing so that binding will be avoided when thebox sides are-distorted, and so that the sleeves at the sides of the axle will be autom lcally aligned by the axle instead of being subjected to cramping when bearings are not truly aligned. Each sleeve is provided with a lug 47 which fits into a corresponding]y shaped note-li i8 in the bearing @i3 to hold the sleeve against rotation in the bearing and a grease-cup is secured in said lug so that lubricant. will be supplied to the b ing surfaces between the sleeve and the axle. If the sleeve should become worn, it can be withdrawn from the bearing and repiaccd with-ont removing or replacing the bearing 43.

The

invention exemplifies a` manure spreader in which provision is made `for preventing the manure from becoming wrapped around or entangled with the tooth-carrying bars; in which provision is made'for prev` venting said bars from cutting the sides of the box, in which provision is made for pie venting excessive wear between the axle and its bearings and which permit ready replacement of the bearing-sleeve when dcsired.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:

l. ln a fertilizer distribnter, the combination of a receptacle for the fertilizer, a cylinder comprising tooth-carrying bars, and a metallic band fixedly secured on the inside of the receptacle and provided with a. member between the ends of the bars and the receptacle sides disposed to prevent the bars from engaging said sides and a fiangc ef;- tending inwardly to longitudinally lap the outer faces of the bars.

2. In a. fertilizer distributer, the combi*- nation of a. receptacle for the fertilizer, a. cylinder comprising tooth carrying bars, and a metallic band liedly secured on the inside of the receptacle and provided with a member between the ends of the bars and the receptacle sides disposed to prevent the bars from engaging said Sides and a flange ei:- tending inwardly to longitudinally lap the outer faces of the bars, said band being noncontinuous and having one of its ends curved longitudinally of and outwardly from the cylinder.
